DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an electronic endoscope apparatus 10 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an electronic endoscope apparatus 10 in the present embodiment.
[0016]
The electronic endoscope apparatus 10 includes a video scope 20 having a CCD 11 and a processor 30 that processes a signal read from the CCD 11. The video scope 20 is detachably connected to the processor 30.
[0017]
A light guide 12 is inserted into the video scope 20. The light guide 12 is an optical fiber bundle that transmits light emitted from the light source unit 22, and the amount of light emitted from the light source in the light source unit 22 is between the light guide incident end 12 </ b> A and the light source unit 22. A diaphragm (not shown) for adjusting the light intensity and a condensing lens (not shown) for condensing the light on the light guide incident end 12A are provided. When the video scope 20 is connected to the processor 30 and light is emitted from the light source in the light source unit 22, the light is incident on the light guide incident end 12A and is emitted from the light emitting end 12B of the light guide 12 on the video scope 20 side. To do. Then, the observation site S is irradiated with the light emitted from the light guide 12.
[0018]
In the light source unit 22, a rotary RGB color filter (not shown) is provided on the light emission side of the light source. The rotary RGB color filter includes a red filter, a green filter, and a blue filter provided at predetermined intervals. For this reason, when the rotary RGB color filter is rotated by the motor, red light, green light, and blue light are sequentially emitted from the light guide emitting end 12B, and these lights are sequentially emitted to the observation site S, and each color is emitted. Are sequentially formed on the light receiving surface of the CCD 11. The CCD 11 photoelectrically converts the optical subject image into an analog signal for one frame, and the generated analog pixel signal for one frame of each color is sequentially read out by a CCD driver (not shown) in the video scope 20.
[0019]
The analog pixel signals for one frame of each color of red (R), green (G), and blue (B) read by the CCD driver are input to the first-stage signal processing circuit 24, and the first-stage signal processing circuit 24 converts the digital image. Converted to a signal. Further, the digital image signal is subjected to processing such as white balance adjustment and γ correction, and stored in the image memory 25 for each color. Then, by adding a horizontal synchronizing signal and a vertical synchronizing signal to the digital pixel signal, a color digital video signal (R, G, B) is obtained. Further, the color digital video signals (R, G, B) are subjected to processing such as enlargement, reduction, noise reduction, and the like, converted into a color analog video signal, and then transmitted to the subsequent video signal processing circuit 26. The color analog video signal is transmitted to the printer 36 after the output level is adjusted by the post-stage video signal processing circuit 26, so that the subject image can be printed by the printer 36. The timing controller 28 controls conversion from an analog signal to a digital signal, conversion from a digital signal to an analog signal, taking in a pixel signal into the image memory 25, creation of a synchronization signal, and the like.
[0020]
On the other hand, in the present embodiment, a monitor 32 having a monitor screen 34 is integrated with the processor 30 so as to be freely opened and closed. If the power switch (not shown) of the processor 30 is turned on while the monitor 32 is closed, which will be described later, the micro switch 38 detects that the monitor 32 is closed, and the detection signal is sent to the system. It is sent to the controller 21.
[0021]
The system controller 21 sends a control signal based on the received detection signal to a CRTC (CRT controller) 29, and further displays a predetermined screen for adjusting luminance and chromaticity that is not related to the subject image based on the control signal. The display instruction signal to be sent is sent from the CRTC 29 to the screen display signal processing circuit 27. The screen display signal processing circuit 27 controls the monitor 32 based on the display instruction signal, whereby an initial screen is displayed on the monitor screen 34.
[0022]
The luminance sensor 40 and the chromaticity sensor 42 provided in the processor 30 detect the luminance value and the chromaticity value at the opposite positions of the initial screen displayed on the monitor screen, and the detected luminance value and chromaticity value are detected. Data is sent to the system controller 21 from the luminance sensor 40 and the chromaticity sensor 42, respectively.
[0023]
The luminance value and chromaticity value received by the system controller 21 are respectively compared with a reference luminance value and a reference chromaticity value already recorded in a RAM (not shown) in the system controller 21 as will be described later. . Setting and changing the reference luminance value and the reference chromaticity value are performed by inputting numerical values using the keyboard 44 connected to the processor 30.
[0024]
As described above, in this embodiment, since it is necessary to display an initial screen at the start of use, a signal necessary for screen display is received from the CRTC 29 and further transmitted to the monitor 32. A circuit 27 is provided separately from the post-stage video signal processing circuit 26. Since the video of the observation site S is also displayed via the screen display signal processing circuit 27, the color analog video signal processed in the image memory 25 is displayed together with the subsequent video signal processing circuit 26 for screen display signal processing. It is also transmitted to the circuit 27.
[0025]
FIG. 2 is a side view of the processor 30 in which the monitor 32 is integrated. FIG. 3 is a top view of the processor 30 with the monitor 32 opened.
[0026]
A monitor 32 having a monitor screen 34 is rotatably attached to the top surface of the processor 30 via a hinge 48 and can be opened and closed in the direction of the arrow. A micro switch 38, a luminance sensor 40, and a chromaticity sensor 42 are provided on a monitor facing surface 46 which is the upper surface of the processor and faces the monitor screen 34 of the monitor 32 in the close state when the monitor 32 is closed. Yes. Whether the monitor 32 is closed or not can be determined by turning on / off the micro switch 38. When the power of the electronic endoscope apparatus 10 is ON, the monitor 32 is closed by the micro switch 38. When determined, a predetermined initial screen is displayed on the monitor screen 34. The luminance sensor 40 and the chromaticity sensor 42 detect the luminance and chromaticity at a predetermined position on the initial screen that faces the luminance sensor 40 and the chromaticity sensor 42.
[0027]
As shown in FIG. 3, a luminance sensor 40 and a chromaticity sensor 42 are located near the center of the monitor screen facing area 50 that is on the monitor facing surface 46 and faces the monitor screen 34 when the monitor 32 is closed. Is provided. At this time, in order to block disturbance light, the monitor 32 is provided so as to be close to or in contact with the monitor facing surface 46 on the processor 30 side when closed. Thereby, the monitor 32 is closed and the initial screen is displayed on the monitor screen 34, and the brightness and chromaticity on the initial screen are detected in a state where the influence of ambient light is small.
[0028]
Each of the luminance sensor 40 and the chromaticity sensor 42 includes at least one pixel for red (R), one pixel for blue (B), and two pixels for green (G). The cell array is located directly opposite the photocell array in the opposite area of the monitor screen 34 when the monitor 32 is closed.
[0029]
FIG. 4 is a front view of the processor 30 with the monitor 32 opened.
[0030]
In this embodiment, when the monitor 32 is opened and an image is displayed on the monitor screen 34, the positional relationship among the monitor 32, the monitor screen 34, the processor 30, and the monitor facing surface 46 is shown as in FIG. It is. At this time, the micro switch 38 detects that the monitor 32 is open, and the display of the initial screen and the detection of luminance and chromaticity by the luminance sensor 40 and the chromaticity sensor 42 both display images. This is performed in a state where the monitor 32 before being closed is closed, and is not performed in this state.
[0031]
FIG. 5 is a flowchart showing a luminance / chromaticity adjustment routine performed by the system controller 21. When the main switch of the electronic endoscope apparatus 10 is operated and turned on, the routine is started.
[0032]
In step S501, it is determined whether or not the micro switch 38 is in an ON state. If it is determined that the microswitch 38 is ON, that is, the monitor 32 is closed, the process proceeds to step S502. If it is determined that the microswitch 38 is not in the ON state, the luminance / chromaticity adjustment routine ends.
[0033]
In step S502, a predetermined initial screen for brightness and chromaticity adjustment is displayed on the monitor screen 34 in a closed state. In step S503, the luminance sensor 40 and the chromaticity sensor 42 detect the luminance and chromaticity at positions facing the respective sensors on the initial screen. When the detected luminance value and chromaticity value data is sent to the system controller 21, the process proceeds to step S504.
[0034]
In step S <b> 504, it is determined whether or not the luminance value (hereinafter referred to as the current detected luminance value) BR detected by the luminance sensor and transmitted to the system controller 21 is a value included in the reference luminance range B. In this case, the reference luminance value B to be compared with the currently detected luminance value BR is a range defined by the upper limit value Bmax and the lower limit value Bmin of the reference luminance range that is set in advance and recorded in the RAM in the system controller 21. is there. If it is determined from these comparison results that the current detected brightness value BR is a value within the reference brightness range B as shown in the expression (1), the process proceeds to step S505, and the expression (2) or (3) When it is determined that the current brightness value BR is a value outside the brightness reference range B, as shown in the equation), the process proceeds to step S506.
Bmin ≦ BR ≦ Bmax (1)
BR <Bmin (2)
Bmax <BR (3)
[0035]
In step S505, the previously detected brightness value Bpre and the previously detected chromaticity value Cpre, which are detected during the previous sensor operation and recorded in advance in the RAM in the system controller 21, are detected by the current brightness value BR and the chromaticity sensor. The chromaticity value transmitted to the system controller 21 (hereinafter, this time detected chromaticity value) CR is compared. Then, it is determined whether or not the previously detected luminance value Bpre and the previously detected chromaticity value Cpre are substantially equal to the current detected luminance value BR and the current detected chromaticity value CR, respectively. Note that the chromaticity is compared for each of the R, B, and G color elements.
[0036]
Whether or not the current detection luminance value BR and the previous detection luminance value Bpre, and the current detection chromaticity value CR and the previous detection chromaticity value Cpre are substantially equal to each other is determined based on the current detection luminance value BR and the previous detection luminance value Bpre. , And whether or not the difference between the current detected chromaticity value CR and the previously detected chromaticity value Cpre is within the preset allowable luminance range Dbr and chromaticity allowable range Dcr. To be judged. These differences are within the allowable luminance range Dbr and the allowable chromaticity range Dcr as shown in the equations (4) and (5), and any of the current detected luminance value BR and the current detected chromaticity value CR. If it is determined that the previous detected luminance value Bpre and the previously detected chromaticity value Cpre are substantially equal to each other, the process proceeds to step S508. On the other hand, as shown in the equation (6) or (7), either the current detection luminance value BR or the current detection chromaticity value CR is substantially different from the previous detection luminance value Bpre or the previous detection chromaticity value Cpre. If it is determined, the process proceeds to step S507.
| BR-Bpre | ≦ Dbr (4)
| CR-Cpre | ≦ Dcr (5)
| BR-Bpre |> Dbr (6)
| CR-Cpre |> Dcr (7)
[0037]
If the brightness and chromaticity values detected during each previous sensor operation have been corrected as described later, the corrected brightness and chromaticity values are the previously detected brightness values. Bpre and the previously detected chromaticity value Cpre are recorded in the RAM. Accordingly, also in this case, the previously detected luminance value Bpre and the previously detected chromaticity value Cpre after correction are respectively compared with the current detected luminance value BR and the current detected chromaticity value CR.
[0038]
In step S504, if the currently detected luminance value BR is a value outside the preset luminance reference range B, as shown by the equation (2) or (3), the monitor abnormality or monitor screen The lifetime of the backlight is expected to be exhausted. For this reason, in step S506, a message prompting the operator to check the monitor 32 or replace the backlight for the monitor screen 34 (when the monitor 32 is a liquid crystal monitor) is displayed on the monitor screen 34 to adjust the brightness and chromaticity. The routine ends.
[0039]
In step S507, the display of the luminance and chromaticity displayed on the monitor screen 34 and the luminance and chromaticity of the initial screen for chromaticity adjustment is performed. That is, the luminance and / or chromaticity at a predetermined position on the initial screen detected by the luminance sensor 40 and / or the chromaticity sensor 42 is detected as the previous detected luminance value Bpre and / or the previous detected chromaticity value Cpre. In addition, a signal for correcting the luminance / chromaticity of the initial screen displayed on the monitor screen is sent from the system controller 21 to the screen display signal processing circuit 27 via the CRTC 29. Based on this signal, a signal for correcting luminance / chromaticity in the display on the monitor screen 34 is sent from the screen display signal processing circuit 27 to the monitor 32, whereby the initial screen display on the monitor screen 34 is displayed. The luminance / chromaticity is corrected.
[0040]
When this correction is performed, the process proceeds again to step S503, and the luminance sensor 40 and the chromaticity sensor 42 detect the luminance and chromaticity at a predetermined position of the corrected initial screen again. Then, with respect to the luminance value and chromaticity value in the corrected initial screen, the same determination and processing are performed again after step S504, and the previously detected luminance value in which the corrected luminance value and / or chromaticity value is an appropriate value. Steps S503, S504, S505, and S507 are repeatedly executed until Bpre / previously detected chromaticity value Cpre is substantially equal.
[0041]
In step S508, values finally detected as luminance values and chromaticity values at predetermined positions on the initial screen are recorded in the RAM. Here, the brightness value and chromaticity value to be recorded are the current detection brightness value BR and the current detection brightness value BR initially detected by the brightness sensor 40 and the chromaticity sensor 42 when the initial screen correction in step S507 is not performed. This is the detected chromaticity value CR. On the other hand, when the correction is performed in step S507, the corrected luminance value Badj and the corrected chromaticity value Cadj, which are final luminance values after correction, are recorded. In any case, the luminance value and chromaticity value recorded in the RAM in step S508 are compared with the luminance value and chromaticity value detected during the next operation of the luminance sensor 40 and chromaticity sensor 42. The value Bpre and the previously detected chromaticity value Cpre are obtained. When the recording of the luminance value and the chromaticity value is finished, the luminance / chromaticity adjustment routine is finished.
[0042]
In this embodiment, after it is determined in step S504 whether or not the current detection luminance value BR is a value within the luminance reference range B, in step S505, the current detection luminance value BR and the current detection chromaticity value CR are Although it is determined whether or not the previous detected luminance value Bpre and the previous detected chromaticity value Cpre are substantially equal to each other, the execution order of step S504 and step S505 may be reversed.
[0043]
Since the luminance value generally tends to decrease with the use of the monitor screen, the upper limit value Bmax and the lower limit value Bmin are not set as the reference luminance range B in step S504, but only the lower limit value Bmin is set. Also good. In this case, as shown in the equation (8), when it is determined that the current detected luminance value BR is a value within the luminance reference range B, the process proceeds to step S505, and as shown in the equation (2). If it is determined that the current brightness value BR is outside the brightness reference range B, the process proceeds to step S506.
Bmin ≦ BR (8)
